Default: 600 (expressed in units of seconds)
Range: 10–1200
Related parameters: controlled_execution
Applies to: Command-line client (dbutility) only

The min_check_time parameter is used in with the controlled_execution parameter to reduce the number of times the program reads the corresponding entry in the DATASOURCES table. After a quiet point, which ends a transaction group of updates, the program only reads the DATASOURCES table if min_check_time has elapsed since the last read. If you set this parameter to 60 seconds, the program reads the DATASOURCES table no more than once a minute, even if quiet points are only a few seconds apart.
